The synthesis of ethyl ()-4-chloro-3-hydroxybutanoate (()-ECHB) from ethyl 4-chloroacetoacetate was studied using whole recombinant cells of expressing a secondary alcohol dehydrogenase of Using 2-propanol as an energy source to regenerate NADH, the yield of ()-ECHB reached 36.6 g/l (more than 99% , 95.2% conversion yield) without addition of NADH to the reaction mixture.

Ethyl acetoacetate-sugar derivatives were prepared by standard alkylation of primary or secondary hydroxyls of diacetonide-protected sugars with ethyl 4-chloroacetoacetate. The obtained d-fructose, d-galactose, d-glucose and d-allose derivatives were conjugated to C60 using the Bingel reaction to afford hydrolytically stable, ether-linked fullerene-carbohydrates. Conjugation of an ester-protected mannose derivative to the C60 scaffold was carried out by the combination of the acetoacetate chemistry with the azide-alkyne click reaction.
